odeint unable to compile without std=c++0x #116

Closed ghost closed 10 years ago

ghost commented 10 years ago

I just had my issue solved on stackexchange - http://stackoverflow.com/questions/19875527/canot-compile-c-which-uses-odeint-from-boost

I had to manually get the latest boost from sourceforge which shipped with odeint and it compiled successfully with both g++ and nvcc nvcc -o example -Xcompiler "-std=c++0x" example.cpp

I have gcc v4.6.3 on ubuntu and 4.7 on Mac. In both cases the following example failed to compile without the `std=c++0x' flag.

I guess its not able to fall back to boost::bind

The example in the stackoverflow thread was indeed from an older version and I changed it to use this which worked with C11 compiler options only -> http://pastebin.com/kY9sPALf

Awesome job with odeint btw :)

Your example compiles perfectly fine for me with g++-4.7 and g++-4.6 and without -std=c++0x. Can you paste your exact output and the compilation command?

Hmm, it seems that boost.config does not work correctly for your setup. There is a define BOOST_NO_CXX11_HDR_FUNCTIONAL which checks if the C++11 header is available at your machine. It looks like this define is not set, alotough you don't have a C++11 compiler. I will look what boost says about this issue.

Thanks for looking into it. This is my setup info, hope this helps:- -Release 12.04 (precise) 64-bit, Kernel Linux 3.8.0-32-generic -Vanilla install with only the CUDA toolkit v5.5 installed to use Thrust libraries -I have replaced the boost from ubuntu repos with the latest version i.e. boost 1.55.0 b1 -Processor - AMD Phenom II X6, 16 GB DDR3 RAM, Nvidia GeForce GTX TITAN

Update :- I have tried out several codes from boost. All of them compiled successfully without the C++11 flag with the exception of odeint and regex libraries

could you try boost.1.54?

Compiled all examples with boost 1.54 without using C11 flags. Seems there is a problem with v1.55.0 Thanks
